[Pawn] How can I position the camera in front of the vehicle?

[Next]

I'm trying to make a system where I need to position the camera in front of the vehicle so that it "points" to the vehicle without setting the coordinates in an array, having a "radius" using a GetVehicleModelInfo function.







I managed to do a function where I can get the front of the vehicle using some calculations. But I can't point the camera at the vehicle at the right angle.

PHP Code:

GetVehicleFront(vehicleid, &Float:x, &Float:y)

{

? ? new Float:a, Float:fSize[3];

? ? GetVehiclePos(vehicleid, x, y, a);

? ? GetVehicleZAngle(vehicleid, a);

? ? GetVehicleModelInfo(GetVehicleModel(vehicleid), VEHICLE_MODEL_INFO_SIZE, fSize[0], fSize[1], fSize[2]);



? ? x = (/* radius using fSize? (about 7.5) */ * floatsin(-a, degrees));

? ? y = (/* radius using fSize? (about 7.5) */ * floatcos(-a, degrees));

? ? return 1;

} 


btw, is this function correct??
